ported on a bracket B on the frame A in opposition to a cutting knife.13 mounted on a knife lever B pivoted on the base A on the spring B. Acam roller 13 on the knife lever B is held by this spring B inengagement with the cam B on a cam shaft B". This cam shaft B isrotatably mounted on B in the frame A and is provided with a miter gearB in mesh with the miter gear B The relative angular positions of thefeeding cams or segments and the cutting cam are such that the cuttingcam operates to cut off the wire only after the feeding cams have fedthe wire forward a suitable distance.

The wire as it is fed forward beyond the cut-off apparatus passes-acrossthe ends of the anvil bars C C. These anvil bars have rotatably mountedthereon sleeves C C which sleeves carry twisting fingers C C pro ectingdown beyond the wire to leave room for the wire between them and theanvils. These sleeves C C are journaled in bearings C supported on theframe brackets C The sleeve C is provided with a ear C in mesh with thesliding rack C"; and the sleeve C is providedwith a gear (1 in mesh withthe gear C which gear is in mesh with the rack C and rotatably mountedon the lug C projecting from one of the brackets C". The rack isslidably mounted on the guides C on the brackets C and has at one end across head C to which it is adjustably attached. This cross headreciprocates in the guide C on the bracket B and carries an arm C whicharm is provided with a cam roller C in engagement with the cam 6 on theshaft A This cam is so angul'arly positioned with respect to the feedcams A A that a reciprocation of the rack takes place only after thewire has been fed in a suitable distance and cut off. The gear C isprovided in order that the two twisting fingers may rotate in oppositedirections in response to the movement of the rack. The spring C isprovided for the purpose of yieldingly holding the rack always againstthe cam.

Intermediate the anvil bars C C and loop forming mechanism is locatedthe mutilated sleeve D supported on a bracket D projecting upwardly fromthe base A. This sleeve is closed for substantially its entire peripherybut opened through an angle of approximately at the bottom. In thisASSIGNOR TO BATES VALVE BAG sleeve is rotatably mounted a twisting headD which head is substantially solid except for an angular slot formin Ian arc of approximately 60 and exten ing slightly beyond the centerthereof to permit passage of the wireA". This twisting head extendsoutwardly beyond either end of the sleeve D terminating in tongues D Aspring D :is fastened at one end to the sleeve D and 0.

at the other to the head D to yieldingly hold the twisting head inposition shown in Fig. 9. Teeth D are cut in the periphery of the head Dand are in mesh with the mutilated gear D on. the shaft B" whichmutilated gear is toothed for such a distance as to rotate the twistinghead through approximately 180. The two ends of the twisting head D areslotted as indicated in Figs. 5,

7 and 8. The slot'is normally narrow but enlarged or deepened as at D onthe side of the head toward the anvils C C and is provided with a camsurface D to guide the 12 and 13.

The anvil bars C C are slidable in the sleeves O C and are provided attheir upper ends with the reduced portions E E? respectively whichreduced portions are engaged by the forksE. E on the rocker arms E Theserocker arms are keyed to the shaft E journaled on the brackets C" and onthe bracket A. This shaft E is provided with a cam arm E carrying a camroller E in opposition to a cam E on the shaft A, the roller being heldagainst the cam by a spring E As the shaft A. rotates the cam E beingangularly arranged so as to operate subsequently to the forming of thetie will rotate the shaft E and lift up the lever E and thus pull up onthe anvil bars and free them from the tie. The wire subsequent toitsbeing cut oil" and prior to the final twisting movement is held inthe head D by the plate G which projects into the slot to hold the wirein position, and is mounted on the rock shaft G and adapted to becontrolled by the lever G provided with a cam roller G in opposition tothe cam G which is carried by the shaft A In order to provide forincreased length of wire tie one of the brackets C is slidably mountedon the base A and the holding bolts travel in the slot A so they may beloosened to give any suitable length of wire. When this is done it isonly, necessary to replace the twisting head D without interfering.

with the operation; The shaft E" is rovidedwith a key-way E to which issplmed one of the arms E to enable the shaft E to lift the anvil. Therack is of suificient length to provide for this adjustment and sincethe movement of the rack is the same at all points alon it the operationof the twisting anvils wil be the same no matterwhat the length of theties produced. The bracket C in order to hold it rigidly in positionwhen locked or bolted is provided with a tongue C and assists inanchoring the bracket C.

The use and operation of my invention.

are as follows: The wire is fed into the-machine from any suitablesource of supply, not here indicated, by the rotation of the two feedingcams which grip the wire and once each revolution feed it forward adistance equal to the peripheral distance during which they are inopposition, which distance may be said to be anything from zero to thetotal periphery of the cam, namely, one-half the circumference, bymerely adjusting the angular position of the two cams with respect oneto the other. When this feeding forward has ceased owing to the feedingcams having passed out of engagement with the wire, the wire cutting camwill cause the wire cutting arm to swing forward toward the wire and theanvil against the yielding pressure of the spring to cut the wire. Thiswire will in the meanwhile be held in position in the downwardly openV-shaped groove in the turning mandrel by the holding plate shown at Gin Fig. 3. While the wire is here held and subsequent to the cutting offof the wire cam 0 will force the rack C to the right in Fig. 1, rotatingthe two vertically disposed twisting mandrels through substantially '270degrees, the pressure of the pin C on the mandrel against the wire willas this pin rotates, cause the pin to slide along the wire and fold orbend it into the shape shown in Fig. 11. The wire will then be grippedon the mandrel and the support of the leaf G will no longer be needed.This leaf is then allowed to drop down and the mandrel D is rotated,bending the ends of the wire about the body of the wire to produce theresult shown in Figs. 12 and 13.

Attention is called to the peculiar shape of the slot D shown in Fig. 8.This slot is broad at the point where the wire enters it in order thatthere may be no possible chance of the wire missing the slot. It narrowsdown, however, as the wire is rotated to bring the end of the wire frombelow firmly up against the body of the wire when it reaches the-part D.Subsequent to this twisting movement the spring D draws the mandrel Dback to the position shown in Fig. 9 and the cam E rocks the shaft E tolift up on the bell cranks E and raise the wire engaging portions of theanvil bars 0, C to draw them out of engagement with the wire tie andpermit the tie to fall freely into any suitable receptacle. All theseacts are performed during the half revolution from the. time when thefeeding cam lets go of the wire to the time when it is ready to againcommence feeding the wire into the machine, although, of course, theremay be a slight amount of lag, as .no harm would result so long as theend of the wire has not quite reached the first mandrel before itreturns to its normal position.
